The first rule states pin-point predictive maintenance does not automatically lead to reliability. This is because most failures do not follow age related patterns. Only advanced sensing technologies will detect potential failures at early stages.
By scheduling regular tasks such as tightening up electrical connections, rebuilding equipment or replacing bearings, predictive maintenance will yield more practical results in reliability.
The second rule is to continue with predictive maintenance strategies even when the times are tough. Technicians should use proven strategies which increase capacity, availability and uptime. Predictive maintenance is useful during difficult times because the overall cost is less than most reactive or time-based maintenance programs.
Rule three claims effective predictive maintenance programs do not consist of only vibration, infrared, ultrasound, motor testing and oil analysis. Although these are important, predictive maintenance tasks should add value by finding failures and eliminating defects in ways that support the overall aim of the company.
Rule four emphasises the importance of networking with other professionals. The experience of others can be very valuable. At maintenance-related events, look out for stories on how others have avoided roadblocks.
